Docker: improved env var handling (#113)

* Improve env var handling, clarify instructions

updateConfig.js will update dist/config.json with any values specified in the docker compose file as environmental variables (env vars). If not specified it will use the default values in src/config.json (the 'usual' place where folks can customize their config).

A user can make changes to an env var (e.g., disabling Scroll Random Results), then docker compose up -d to quickly restart the container with the change.

* minor update to env vars in table

Make sure to change your compose so the updated flattened values work.

* TZ handling for cron runs of the script

docker logs netsky should now show the proper time zone for script runs that were initiated via cron schedule.
